Title: Electric pulse-responsive device
Inventor: EDWARDS HUW BRYANT
IPC: H04M15/10
Filed: 1961-03-10
Abstract: 927,462. Counters. ERICSSON TELEPHONES Ltd. Jan. 15, 1962 [March 10, 1961], No. 8953/61. Class 106 (1). A latching relay energizes in alternately opposite directions in response to the terminations of successive pulses. When contacts 1 close to the first pulse capacitor 6 charges in a first sense. When the contacts open at the end of the pulse the capacitor discharges in the direction of the arrow to energize relay 3 appropriately. Contacts 2 and 7 change over. The next pulse acts in the reverse sense so that at its end relay 3 energizes in the opposite sense and contacts 2 and 7 restore. A number of such circuits can be joined together to form a binary cascade counter (Fig. 2, not shown). Fig. 4 shows a decimal variant. The eighth pulse energizes relay D in an upward sense, the ninth relay A also. The tenth pulse restores A and D so that all four relays A-D are energized in a downward sense. Transfer to the next denomination is effected over contact d2 in series with an a contact (not shown). Resetting may be effected at any count by operation of the contacts ka1-ka5. The count may be indicated by a cascade of contacts delivering a signal to one of ten terminals.

Title: Improvements in the production of yarns, threads, cords and ropes
IPC: B60C9/00
Filed: 1946-03-22
Abstract: Yarns, threads, cords and ropes of highly polymerized linear esters of glycols of general formula OH(CH2)nOH where n is greater than 1 but less than 10 with terephthalic acid are made by a process comprising the step of twisting together a bundle of filaments, and drawing in the solid state before and/or after the twisting step. Suitable glycols are ethylene, trimethylene, tetramethylene, hexamethylene and decamethylene glycols, and these may be heated with terephthalic acid or any of its aliphatic or aryl esters and half esters, its acid halides, ammonium and amine salts.  Preferably polyethylene terephthalate (M.P. 240 DEG  C.) is used.  The filaments already drawn to 600 per cent are further drawn to remove residual stretch of order of 1-20 per cent if desired by drawing at a temperature at least as high as that of the original drawing but not higher than 30 DEG  C. below the melting point of the polymer.  Heat setting may also be carried out while the articles are under tension by heating to a temperature at least as high as the drawing temperature but not higher than 30 DEG  C. below the melting point. Yarns so produced have strength of 4-8 g/denier, and may be of any thickness, say 10-20,000 denier, and may be utilized in weaving or knitting operations.  Threads are particularly useful as sewing thread.  The polymers being resistant to moisture, salt water and bacteria are of use in the production of marine ropes and ropes for the chemical industry. In an example a highly polymeric ethylene terephthalate is melted, filtered through a sand pack and extruded into filaments.  The filaments are wound on to a bobbin giving a yarn of 105 denier. Three such yarns are wound on to a common bobbin to give a 30 filament yarn of 214 denier, which is cold drawn to 5.5 times its original length and twisted on to a cone to give a 30 filament yarn of 60 denier having 1.5 twists to the inch. Specification 603,840 is referred to.

Title: Improvements in carrying out the reaction of carbon monoxide with hydrogen
IPC: B01J23/74
Filed: 1936-03-26
Abstract: In the thermal conversion of carbon monoxide and hydrogen into hydrocarbons having more than one carbon atom and/or their oxygen-containing derivatives, the catalyst is prepared by adding to a previously precipitated reducible compound of a metal of the iron group a compound of another metal, which on heating yields an oxide not reducible by hydrogen below 900 DEG  C., and subsequently heating the mixture in a reducing gas to a temperature above 500 DEG  C. so that a partial sintering of the catalyst takes place.  The non-reducible ingredient may be a compound of an earth metal, e.g. aluminium, beryllium, manganese, zinc, thorium, cerium, or zirconium. It may be added in the form of a precipitate or of an aqueous dispersion or solution, which last may be precipitated after admixture with the iron metal compound.  A third component consisting of a compound forming a reducible metal oxide, e.g. copper nitrate, may also be incorporated in the mixture. According to an example, moist precipitated ferric hydroxide is mixed with a suspension of aluminium hydroxide, dried, and reduced in hydrogen at 850 DEG  C. The product contains 5 per cent of alumina with respect to the amount of metallic iron.ALSO:A catalyst for reactions between carbon monoxide and hydrogen is prepared by adding to a previously precipitated reducible compound of a metal of the iron group a compound of another metal, which on heating yields an oxide not reducible by hydrogen below 900 DEG  C., and subsequently heating the mixture in a reducing gas to a temperature above 500 DEG  C. so that a partial sintering of the catalyst takes place.

Abstract: 725,143. Insulators. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 10, 1952 [April 14, 1951; July 4, 1951], No. 9198/52. Class 36. A lead-in insulator surrounding at least one conductor and having a metallized internal surface in contact therewith is formed with at least one metallized groove in the middle portion of its external surface which is in electric contact with a metallic member through which the insulator passes and which is preferably shaped so that at least one of its edges makes approximately a right-angle with the external surface of the insulator. In one embodiment the conductor C is secured within the insulator 5 by nuts 4 which make electrical contact with a layer 6 of silver paint. A supporting collar 8 is bordered by grooves 7, the edges of which meet the surface of the insulator at 90 degrees. The collar and grooves have a coating 9 of silver paint, and the insulator is held in plate 1 by claws 2. The edges of the silvered areas have a coating 10 of plastic material. The purpose of the arrangement is to ensure that in the atmosphere surrounding the insulator there is a weak potential gradient, thus retarding the occurrence of corona effects. The insulator may be modified to carry a conductor of non-circular cross-section, or more than one conductor. The collar 8 may be dispensed with, the insulator then being provided with a single groove, the claws 2 being shaped to engage the surface of the groove. A member having a conductive surface may be inserted in the grooves, in contact with the metallized surface. In order to secure the insulator to the plate a metallic ring in one or two pieces may be soldered or welded to the collar 8 or, where this is dispensed with, to the surface of the groove. Alternatively metal may be cast in the groove to form a mounting ring.

Abstract: 160,819. Ges. f³r Drahtlose Telegraphie. March 31, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic oscillation generators.-It is stated that, when the grid and anode circuits of an oscillating valve are so coupled as to be generating a maximum output of energy, the plate voltage may be varied over wide limits without affecting the wave-length emitted to a greater extent than two per cent. This effect is utilized by applying to the anode of the valve an alternating voltage, of a frequency above audibility, say 5000 per second. Only the positive half-cycles are operative, and these produce variations in the emitted wavelengths which combine to give rise to a beat note in the receiving telephone.
